BRAKE FOR HORSE- POWERS.

SPECIFICATION forming part of Letters Patent No. 310,436, dated January 6, 1885.

Y Application led October, 1884. (No model.)

To @ZZ wwnt it may concern:

Be it known that I, BYRON J. IRIsH, a citizen of the United States of America, residing at Hague, in the county of Varren and State of New York, have invented certain new and useful Improvements in Brakes `for Horse- Powers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation'to improvements in automat-ic brakes to be used on horse-powers; and it consists in the novel construction and arrangement of devices, all as will be hereinafter more fully explained, and particu larly pointed out in the claims appended.

The annexed drawings, to which reference is made, fullyillustrate myinvention, in which Figure l represents a side View of a horsepower frame, showing my improvement, and Figs. 2, 3, 4, 5, and 6 are detail views.

Referring by letter to the accompanying drawings, A designates one side of an ordinary horse -power, and B is the belt-wheel carrying the belt C.

D represents a horizontal lever, which is pivoted at a to the side of the frame A, and the same is provided near its center with a brake-shoe, b, which latter is slotted, as at c, to receive pieces of leather, d, that face the periphery of the belt-wheel and which receive the wear when the shoe comes in Contact with the wheel. To the outer free end of the lever D is pivoted a bar or link, e, the end f of which is pivoted to a vertical lever, g,which in turn is pivoted at its lower end to a bearing on the power-frame, as shown at 71. Near the beltwheel aforesaid, and secured to the side of the frame A, is an angular bracket, z', upon the arm j of which is pivoted an angular lever, k,

to the arm Z of which is swiveled a bail, m, through which the beit passes, and to the other arm, a, of said lever k is pivoted one end, o,of a rod, p,which is provided with a hooked end, q, and slides through a staple-eye, r, on the frame aforesaid.

It will be seen from the above description and by reference to the annexed drawings that should the belt leave the wheel the weight of the same (the belt) will draw down the bail, thus drawing the rod forward, and by the hook end throw down the vertical 1ever, and thereby dropping the outer end of the brake-lever, and by its weight the shoe is pressed upon the periphery of the belt-wheel, thus stopping the same immediately and avoiding accident Should it be desired, a weight may be attached to the free end of the brake-lever.

Having described this invention, what I claim, and desire to secure by Letters Patent, Is

l. In a brake for horse-powers, the slotted shoe provided with leather wear-plates, in combination with the lever D and means, as described, for automatically operating the brake, substantially as specified.

2. In al horse-power brake, the combination, with the lever D, belt-wheel, and frame, of the lever y, rod p, bracket t', angular arm 7c, and loop or bail m, the whole arranged and operating as described, and for the purpose specified.

In testimony whereof I affix my signa-ture in presence of two witnesses.
